IMPROVEMENT IN MECHANICAL MOVEMENTS FOR ACTUATING- PRESSES.

The Schedule referred to in `tlieee Letters Patent and making part o!the same To all whom it may concern Be it known that LPLATT 0.1NGERS0LL,of Green Point, in the county of Kings, and State of New York, haveinvented a new and useful Improvement in Mechanical Movements forActuating Presses, and other purposes, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawing, forming part of this specification, and in which- Figure lrepresents a longitudinal vertical section of a baling-press, having myimprovement applied to it;

Figure 2, a plan of the same; and

Figure 3, au end elevation thereof.

Similar letters of reference indicate corresponding parts.

Referring to the accompanying drawing- A' represents the frame of thepress;

B, its cap or cover, made removable, on throwing down or back swinginglocking-straps C C; and

D, the follower, that may be guided in its 11p-anddown play by means ofend projections or extensions aa of it, arranged to fitvertical slots bb in/the frame.

Secured to the frame, on opposite sides of it, are brackets E E, whichserve to form bearings for shafts c c of double or dividedratchet-wheels F F, having a chain-pulley or barrel-body, G, in between,and connected with or forming part of them.

H H are levers, working on the shafts c c as a fulcrum, and carryingpawls I I, thatas the levers are depressed, serve to give motion to theratchet-wheels F F, which are locked, or prevented from workingbackward, by check-pawls l' l', excepting` when it is required to runthe follower D down or hack, when the pawls I 1 may he ythrown ont ofgear, by pullingr on cords d d.

The lift ofthe follower D, through the levers H H, pawls I I, andratchet-wheels F F is effected by the agency of chains J J, workinground sheaves or pulleys, substantially as follows:

Said chains, which have their one end hangingloose, g

are passed up around the chain-pulleys or bodies G G,

down and around sheaves or pulleys K K, secured to the follower, and upto links or hooks L L, which is the arrangement represented at theleft-hand of figs. l and 2; or, instead of the chains heilig hitched onto the upper hooks L L, they may be passed around a loose pulley, M,arranged on either spindle o, and be hitched or hooked to the follower,as at e, which is the arrangement shown in iig. 3, and at the right-handof gs. 1 and 2.

Ot' course, this latter arrangement increases the power of the press,and may be employed with advantage toward the close of thepressing-stroke, while a quicker and less powerful action may bepreviously used, by adopting the first-mentioned arrangement, which maybe readily changed, when required, to in` crease the power, byunhitching the chains from the hooks L, passing them around the pulleysM, and fastening the-m, as at e, to the follower.

Again, when required to work the press still quicker, as on starting it,the same may be done by a mere direot'pull on the loose ends ot' thechains, instead of working the press by the levers H H.

Thus, not. only is there secured to the press a. wide range of motions,as regards its speed or power, at.

different points in the stroke, or as the resistance of the substancebeing pressed makes necessary ordesirable, but the means for operatingeach end of the follower is independentvof the other, so that increasedpressure or action may be given to either one side 0r the other, as notluifrequeutly is desirable.

That is here claimed, and desired to be secured by Letters Patent, is

The arrangementof the double or divided ratchetwheel or wheels F F, theinterposed connecting-chain pulley or body G, the lever or levers H,with their pawls I, the pulleys M, sheave or sheaves K, and thel chainor chains J', substantially as specified.
